10 nylon plastic screw sets, M4 nut, washer & bolt 40MM

10 Nylon Plastic Screw Sets, M4 Nut, Washer & Bolt 40mm. Ideal for bolt-on-wings airplane model makers. Very lightweight and rigid, when used it flexes but not breaks. During impact it snaps to minimise the damage. To make the most out of it, never use bolts larger than necesary and make sure the block in the fuselage that the bolt threads into is flush with the wing.
